I suppose the hda3 and hdc3 are to be the swap devices, so all you
have to do is:
(1) turn hda2, hda4, hdc2 and hdc4 into _physical volumes_, using
partition id 8e and pvcreate, eg
"pvcreate /dev/hda2 /dev/hda4 /dev/hdc2 /dev/hdc4"
(2) create a _volume group_ out of these PV's
"pvcreate <name of VG> /dev/hda2 /dev/hda4 /dev/hdc2 /dev/hdc4"
(3) create a _logical volume_. This is where the filesystems are
put on :)
"lvcreate -n <name of LV> -L 88G /dev/<name of VG>"
(4) make filesystem
"mkreiserfs /dev/<name of VG>/<name of LV>
that should be it.
good luck,
Nils
